web性能之资源加载时间分析【Resource Timing】【原创】

由 让人想犯罪 __ 提交于 2020-04-06 10:41:11
简介 在前面一章我们学习了 Web Performance Timing Api 可以用来分析web应用的资源加载、手动卡点的性能（时间），那么我们现在就来看看怎么使用 Resource Timing 来分析我们的静态资源的加载情况。 案例： 在平时开发的时候，我们常会遇到这样的问题反馈； 客户反馈 ：朋友我怎么感觉我们这个应用怎么初始化加载就这么慢呢？到底是什么原因时快时慢的？ 开发 ：我用我的(手机|电脑)测试了没有问题啊很快啊，而且我也用谷歌调试工具看了渲染时间确实很快啊。 这个时候对于我们开发来说，我们能想到的方式就是： 先确认是否有脚本加载阻塞 确认是否有资源加载过慢（本机，自己的网络） 对于用户说的慢，其实我们自己也不知道是说的什么慢，然后就各种网上搜一波，优化一波，到底解没解决问题自己是测试不出来的（不知道有没有人跟我一样的感觉就是：开发的设备运行都没有什么问题，到了其他设备上就开始出问题了）。 其实遇到这个问题的最根本的原因是我们无法用 **数据来证明 **到底是哪里慢，什么情况慢，并且我们也无法提前预知到这些问题，总不能让客户把他的设备（手机|电脑）邮寄给你，然后你开始各种调试吧。 其实上面的这个案例牵扯很多的问题： 不知道用户当时的实际网络情况 ☆☆☆☆ 不知道我们的代码在用户的设备运行情况 ☆☆☆ （本章不讲）

Stop CSS3 animation jumping

由 丶灬走出姿态 提交于 2020-01-14 10:29:27
问题 I have the following fiddle (Wekbit/Chrome only). Just watch the animation for a while and you will see it "stop" for a millisecond and then continues again. Could it be the svg file itself? If that is the case, how can I fix this file so the hiccup is gone? HTML <div class="tile10"></div> CSS @-webkit-keyframes move { 0% { background-position: 6px 0; } 100% { background-position: 6px 80px; } } .tile10 { width: 80px; height: 80px; position: absolute; background: url(http://www.mauricederegt

问题 This is related to Creating a peek in effect with animate.css which was answered via using overflow:hidden , but does not work with column-count: I am using the excellent animate.css library for animations. I was wondering if its possible to create a "peek in" and "peek out" effect that is similar to the SlideIn/SlideOut but with the following difference: slideOutRight +-------------+ +-------------+ | | | | | | | | | +---------+ | +---+----+ | | anim | | | anim | | +---------+ | +---+----+ |

Unique grunt globbing issue

由 我只是一个虾纸丫 提交于 2019-12-13 18:32:28
问题 Animate.css is an amazing library that I'm pulling into my project via bower (can't change the folder name). Unfortunately, the folder's name is "animate.css". I want to glob in my whole project (including bower_components) for /**.*.css . Unfortunately, grunt gets angry because animate.css is a folder, not a file. I need a way to ignore the folder, but not the file. Any tips? Here's what my task looks like now: cssmin: { deploy: { files: { '<%= config.prod %>/styles.min.css': ['<%= config
